You could also try other food items to get them started such as mice, gerbil or chicks. Once they start taking these you may be able to move them over to frozen thawed rats from there.

I wouldn't worry too much about the substrate. As long as it isn't ingesting huge amounts there shouldn't be any issues.
BPs can be extremely finicky. I would stick to mice and rats, especially while trying to transition from live to F/T.

Sticking to familiar scents is probably the most efficient way to transition and get the animal eating consistently.

The risk of offering other prey items is that the snake may decide to only eat one of the other, less common, more expensive prey items.

My two cents : keep it simple and stick to what works reliably.
